Developing countries will need to be involved if a future international agreement is to be effective in slowing climate change. Under the Kyoto Protocol’s first commitment period(2008–12), developing countries have not got emissions targets, and the United States have opted out. Whether the Kyoto Protocol will live and have ‘teeth’ in future depends on negotiations which are due to formally begin in 2005. Current conflicting positions between developing countries, the United States, and Europe appear entrenched, but progress could be made towards cooperation if developing countries’ interests are paid heed and a balance on equity issues is achieved. This paper interprets some of the politics and economics surrounding developing country participation in international climate policy, including future emissions targets, the Clean Development Mechanism (CDM), and adaptation to climate change
